How the lookups work

Percentage = correct ÷ total × 100. The letter grade uses the exact percentage before any rounding, on the standard US scale (A 90%, B 80%, C 70%, D 60%). Each page also shows the plus and minus scale and the stricter 7-point scale, because schools differ. For a whole test, use the grade calculator or print a grade chart.
